PACKING DEVICE FOR PAPER-FOLDING AND SIMILAR MACHINES.

SPECIFICATION forming part of Letters Patent No. 277,806, dated May 15, 1883. Application filed January 6, 1883. (No model.)

To all whom it may concern:

Be it known that we, JOHN H. STONEMETZ.

and WALTER G. BENNETT, citizens of the United States, residing atErie, in the county of Erie and State of Pennsylvania, have invented certain new and uset'nlIm provements in PackingDevices for Paper-Folding and Simil ar Machines; and we do herebydeclare the following to be a full, clear, and exact description of the inventiomsuch as will enable otherssaid machines. The manner of this application and gearing will vary in accordance with the requirements in the various instances.

Our device consists, essentially, of a revolvin g helical conveyer placed in the packing-box or frame in such a manner as to receive the papers, envelopes, bags, or cards edgewise between the coils of its helix in a plane transverse the axis of said helix, and to convey the same as it revolves broadsidewise to a bunch which forms at its end.

The construction and operation of this device can be greatly varied in details and yet preserve the above essential details or features.

Ve have, in the accompanying drawings, shown the device in connection with a paperfolding machine, showing, however, only a fragment of said machine, suiiicient only to properly illustrate the manner ofapplying and operating the said device in one of the many methods of its use or application.

In the drawings, Figure l is an end View of the device seen from the side of the foldingmachine. Fig. 2 is a side view of the device seen from the end of the folding-machine. Fig. 3 is a top or plan view of the doviceand the packing-box, frame, or rack.

The construction, adjustment, and operation,

as illustrated, are as follows: I is the packing frame or box, and H the adjustable end piece. Gr represents a forming package of papers,

and G papers being conveyed into the formin g package.

D is the conveyor-shaft, which is mounted in proper hearings in the box or frame 1.

The conveyor is formed of two concentric I helices of unequal diameter, but of uniform pitch, (marked E and F.) The object of these .two helices is to have two ends, so as to give a more even and uniform pressure upon the package. This same result might, however, be accomplished by making the helix of wider material and having its outer end considerably expanded. The conveyer is so adjusted as to lie partly below the bottom of the box I, and a grating formed of strips J J J furnishcs a bottom within the conveyor. The coils of the helix are sufficiently spread apart to receive the object to be conveyed edgewise. When used with a folder connected with a press having an accumulating-cylinder, the coils will be wide enough apart to receive the bunches of papers as they fall from the folder. In such a case the conveyor may be made long and convey the bunches outside of the machine,

where they may be picked out before reaching the end of the shalt, working loosely, but communicating motion to the shaft by a one-way clutchorratchetdevice. (Notseem) Astrap,b,

connects with a wrist-pin, a, on the gear A of the folder, and winds upon the part B of the drum. A strap, 0, having a weight, 0, winds on the part 0 of the drum. The operation of this gearing will be understood without explanation. By it the conveyer is rotated at intervals, and the size of the drums will regulate the number of revolutions the conveyor will make at each interval, which may be one or more, as desired.

WVhat we claim as new is- 1. In a bunching or packing device for paper-folding and other machines, the combination, with a frame or box, of a helical conveyer arranged longitudinally therein, in a manner substantially as shown, whereby it will receive the papers or other objects edgewise between its coils, and when rotated convey the same broadsidewise along the said box or frame, substantially as and for the purposes mentioned.

2. In a bunching or packing device for paper-folding or other machines, thecombination, with a frame or box, of a conveyer arranged longitudinally therein, which is composed of two concentric helices of differing diameters and substantially uniform pitch, andis adapted to operate substantially as and for the 'purposes set forth.

3. In a bunching or packing device for paper-foldin g or other machines, the combination, with a frame or box, of a helical conveyer arranged longitudinally with and partly aboveand partly below the bottom of said box or frame, substantially as shown.

- diameters and substantially uniform pitch, and z 5 is adjusted so as to lie partly within and partly without said box or frame, which is grated, as at J J J, so as to intersect said helical conveyer, substantially as shown.

In testimony whereof we affix our signatures 0 in presence of two witnesses.
